Though researchers have seriously questioned the feasibility of Dr. Canavero's plans, it seems the first human head transplantation is a step closer to becoming a reality; Valery Spiridonov, a 30-year-old computer scientist from Vladimir, Russia, is the first person to volunteer for the procedure. Spiridonov has Werdnig-Hoffman disease - a rare genetic muscle wasting condition, also referred to as type 1 spinal muscular atrophy (SMA). The condition is caused by the loss of motor neurons in the spinal cord and the brain region connected to the spinal cord. Individuals with the disease are unable to walk and are often unable to sit unaided.
